application led April 21, 1921. Serial No. 463,429.

T 0 @ZZ fw hom t m cn/ concern Be it known that I, @einem iri'rzr:7 a citizen ot the United States ci? 'nt-rrica, and resident ci the city of Seattle, in the county o'f King and ot ll/Yishinggton, have invented certain new and useiful improve ments .in Ca-bleways7 ot which the 'following is a specitication.

My invention relates to cableivays and particularly to a type of cableway which is particularly designedv for use in logging.

The object ot my invention is to provide .means whereby ca-bleways olE this character may be conveniently and quickly shifted in position, as is required by the nature of the work, so that the cableway may be moved as may be required for the progressive logging of ka considerable area.

rlhe object ot the invention, more specilically stated, is to provide means whereby thef outer or tail end of the cableway may be laterally shifted for operation over a new strip of ground.

The construction and `operation et a device embodying my invention will be hereina'fter described and the particular features thereof which l believe to be new and upon which l desire to secure Letters Patent will then be particularly defined by the claims.

lln the accompanying drawings l have illustrated a type oi construction torcarrjrine* out the purposes off my invention which i ,Y is oit the design now preferred by me.

Figure l is a diagram showing a cableway or` the type with which my invention 1s iutended to be employed, the saine showing the c location of my improved constructions.

Figure 2 is a diagram showing in plan. the

manner or applyingmyinvention to shift the tail end of the `cableway laterally to a new location.

Figure 3 shows in elevation on a larger scale, the manner ci. applying my invention. Figure 4 is a diagram showing' in plan the particular type of engine which would pretof this character. K v

Figure 5 is a diagram showing in plan a modiiied manner ot operating; my invention in shiftingf the cableway.4 y l It is one of the purposes of my invention to provide means whereby the power of the cableway and its operating engine be employed for the shiftingy of the tail end of 'the cableway'to a new location laterally fre- .moved from the former.V The type of cable `little length. 40 with the tail block 2 is y ccrners tor way for which my invention is peculiarly passes about a sheave or block, ln such a cableway the main or traclrwayline is capable of being operated se as to let out one side and haul in the other or to let out or haul in both sides at the same time, as may be desired or necessary.

ln the particular cableway shown in the drawings such a looped or double main line is employed consisting ofthe two sections l and l0, the outer .or looped end of which passes about a tail block 2. rEhe inner ends of this line extend to and are secured keach to its respective one of the drums 3 and 30. These are the drums which, `in thetype oi: engine illustrated are located nearest to the boiler. These drums are desi gned to vbe operated by` their engine, either both together or one at a time, asmay be desired. pon thecableway .is a carriage l5 which is caused to travel thereon by the means ot a hauling linel and a back haul line 17. ylhe latter is returned to the engine through any :convenient route, being` guided by sheaves or blocks .s at suchpoints where this may be needed.

ln a cableway built in accordance with my in-.iention7 the main line tail block 2 is not secured or coupled close to vthe tail tree 4, but is supportedby cable",` as ILO, ot some The connection ot' 'the cable i through the medium et a membenas 5, whichserves a double purpose, first to steady thisline in such manner to prevent rotating oi the block as a whole about an axis extending in the direction of the cableway, and second theretok the shittingr line by which the tail end oit the cableway is shifted from one location to another.

in Figure Bis in the form ofl a triangular plate provi led with means at each oi 'the attachinga line thereto and also provided with means 'for making; attachment thereto at pointsintermediate oi the corners. 7lhe tail block 2 is secured .by a shackle or any other suitable means to one corner of the triangle and the sui-porting; line 40 to am other corrieri' i Secured to thethird corner i'sthe steadying line which is placed so as to extend laterally from the direction of the cableway and line 40. Suicient tension. is placed upon the line 5() to resist any tendency of the plate 5 and the tail block connect-'ed therewith turning aboutmthe algisrot' the cabl'eway. It is important, in operating a cableway oi' this sort that `the `bloclt 2 be held so as to eXtend in a vertical plane, as otherwiseI the lines might becoine twisted andthe operation jof the carriage thereon be prevented.. lBy, providing a member as the plate5,which is secured incr to the suspendingsupport, for the tail block 2 asthe line 4Q, and securing thereto a steadying line, as 50, turning `oi! the block about the axis of the cableway will be prevented. y

When it is desired to shift the ,tail endet the cableway, a block as 7, is secured in elevated position to the new tail tree 70.

. Through this is run the shifting line 7l,

One end kof this line is secured to one of the sides l ,or 1Q of the inain line of, the cableway. This may be ldone by any convenient means. yInithe drawings l have shown l. clamp@ which vis adapted to be securedy to the cablewaylinekand to have the shifting line7l secured thereto.y The otherendof the shitting line 7l vis secured to the ztail block of the cableway.

While this might. be directlysecured to the tail block itismoreconvenient to secure it to thetail block indirectly, or throughy the medium of the plate r5. shown this end ofthe shifting line as being securedby afshaclileto one of the intermediate holes inthe `plate 5. y

In the plan ofy operation illustrated in Eigures 2 and 3, this shifting line passes, between the block .7 and thevtail block of the cableway, througha second block, as l73, which has secured thereto `a snubbinglineS. This snubbing line is passed about either the tail ltree or a stump ora tree ad]- acenttothe old location. In making the shift, the main cableway lineis operated so as ,to hauhin upon the .shifting linewhich has been secured thereto. The `iirst eliifect ofthi's will beto .slacken thstrain upon the line 40 bywhich the cableway hasnheretofore been ,connectedwith andsupported from the tail tree; `The cableway mayjthus be con`ven-` iently disconnected from thetail tree. When 'f thishas been done, further hauling in of the Shift line 7l, thwgh. the @Pfatflon of the main line 1 and: atA the same, time suitably .lettingfout or Islacking,oft' upon thesnubhing line 8, willcauseftheend ofthecablewaytombeshited across from the old locafento the new, at which place the .tail block [2 may,y through .manipula-tim ogf the Shifting line. 7,11., be..dewn.iowards theA mil tree as necessary or desired, and theffnormalpsup porting tackle, consisting of the line ysimilar l have thereforey it in the air, so that in shifting across, the

cableway need not engage with any objects on the ground. The blocks and lines eniployed in shitting the cableway and in securing it at the new location maybe put in place while the cableway is in operation at the old location. ligt isa matter of buta `few minuti-2sV to inalc the necessary connections and to shift the cableway to the new location. This has been done inas short a time as ii'teen Ininutesvand this for a cableway of very long span, approximately one mile span. lt is thus seen that this` particular mechanism contributes very materiallyy to maintaining the cableway in condition for uninterrupted operation.l y

ln Figure 5 ,a slight modification is shown. ln thisfcase they snubbing line 8v is not provided with a. sheave or bloclf. through which the shifting' line 7l passes, but is connected directly to the tail block or to the plate 5 which would be the equivalent thereof. Other than this the operation'oi the device as shown in Figure 5 would be as previously described. v Y 4 Y What I claimasmy invention is: l A
